U.S.–Iran Nuclear Deal Nears Finish Line as IRGC Holds Veto Power
A senior U.S. official puts the odds of closing a new nuclear and sanctions relief deal with Iran at 80%, but says the Revolutionary Guard has yet to sign off. As Tehran’s foreign minister insists enriched uranium will be diluted “within Iran,” the talks now hinge on whether security hardliners allow diplomacy to override battlefield leverage.
Diplomats on both sides of the U.S.–Iran standoff say they are closer to a deal than they have been in years, but the decisive voice may not belong to negotiators in suits – it sits with Iran’s Revolutionary Guard and its view of the battlefield.
On 12 June, a senior official from the Trump administration stated they were “80% confident” that an agreement with Iran could be finalized in the coming days. The emerging framework, as described, would see Tehran commit not to develop or acquire nuclear weapons and to destroy its stockpile of highly enriched uranium in return for sanctions relief. Yet the official emphasized that Iran’s Islamic Revolutionary Guard Corps (IRGC) had not yet endorsed the deal, leaving a critical veto player unconvinced. In parallel, Iranian Foreign Minister Abbas Araghchi, speaking on state television, stressed that “the only way to resolve the issue of materials enriched to the level of 60% is to dilute them within Iran,” signaling Tehran’s red line against shipping sensitive material abroad.
For ordinary Iranians, the stakes are direct: sanctions relief means potential access to frozen assets, fewer barriers to trade, and some easing of inflation and unemployment that have eroded living standards for years. For American households and businesses, a durable deal could reduce the risk of oil market shocks and the possibility of another Middle Eastern war, even if the connection is less immediate. Families on both sides who have lived through cycles of threats, drone strikes, and proxy clashes have reason to regard a verifiable cap on the nuclear file as a step away from open conflict.
Strategically, the contours of the deal point to a familiar but fraught trade: Iran reining in its most sensitive nuclear activities in exchange for economic breathing room. Araghchi’s insistence that dilution must occur “within Iran” preserves domestic pride and sovereignty but complicates verification and trust. For Washington and its partners, any arrangement that leaves enriched material on Iranian soil, even in a less dangerous form, will invite scrutiny from skeptics in Congress and from regional allies like Israel and Gulf states who see the program as a latent threat. For Tehran, agreeing to destroy highly enriched stocks would curtail its most immediate breakout leverage, but it may calculate that its missile forces, regional allies, and control over maritime chokepoints still provide substantial deterrence.
The IRGC’s unresolved position looms over the process. As the institution that controls large segments of Iran’s missile program, overseas operations, and key economic sectors, the Guard must weigh what it might lose in sanctions revenue and procurement opportunities against what it could gain in reduced military pressure and domestic stability. Its commanders are also attuned to battlefield narratives: Araghchi himself framed the timing of an agreement by saying, “The best time to end a war is when we have the upper hand… We have stood for 40 days against what is considered the world’s superpower.” That language suggests Iran’s security establishment wants any deal to be read internally not as capitulation, but as a victory locked in from a perceived position of strength.
If the IRGC ultimately blocks or dilutes the agreement, the likely result would be a return to incremental escalation: more sanctions designations from Washington, more nuclear advances by Iran, and a higher risk of miscalculation in hot spots from the Gulf to Israel’s northern front. Conversely, if the Guard signs on, the architecture of the deal will have to be robust enough to satisfy inspectors and skeptical legislatures while giving Iran enough tangible economic relief to justify compliance at home. That balancing act has undone previous efforts.
Key Takeaways
- A senior U.S. official estimates an 80% chance of closing a new nuclear and sanctions relief deal with Iran in the coming days.
- The prospective agreement would commit Iran not to develop or acquire nuclear weapons and to destroy its stockpile of highly enriched uranium in exchange for sanctions easing.
- Iran’s Foreign Minister Abbas Araghchi insists enriched material must be diluted “within Iran,” rejecting removal abroad.
- The Islamic Revolutionary Guard Corps has not yet approved the deal, leaving a powerful domestic actor in a potential veto position.
Outlook & Way Forward
In the immediate term, observers should watch for synchronized public messaging: statements from Supreme Leader Ali Khamenei, senior IRGC commanders, and Araghchi will indicate whether internal resistance is softening or hardening. Any new round of Iranian missile launches or maritime confrontations, particularly in the Strait of Hormuz, could either be leverage for the final bargaining or a sign that hardliners are steering away from compromise.
If a deal is signed, the next phase will be implementation and verification – re-establishing monitoring, sequencing sanctions relief, and managing inevitable violations and disputes without letting them collapse the arrangement. If it fails, Washington and regional capitals will pivot back to containment and pressure strategies, with Iran likely accelerating aspects of its nuclear and missile programs. In both scenarios, the IRGC’s calculus – whether it sees more security in a controlled opening or in enduring confrontation – will shape not just the fate of this negotiation, but the region’s stability for years to come.
